Abstract (en)
[origin: WO2009040742A2] It is provided a method for imaging a dynamic process in a part of the body, especially blood perfusion, with an x-ray system as well as corresponding apparatuses and a corresponding computer readable medium. Especially it is described a method for imaging a dynamic process in a part of the body, especially blood perfusion, with an x-ray system, comprising: acquiring rotational projections of the part of the body over an angular range (2), deriving the anatomy of the part of the body subject to the dynamic process using a tomographic reconstruction from the projections (3), determining an optimal position of the x-ray system according to the derived anatomy for acquiring projections of the dynamic process (4), administering contrast agent to the part of the body (5), acquiring projections of the dynamic process from the determined position (6); calculating the dynamic contrast enhancement over time (7); and calculating and displaying perfusion parameters (8).
